Application filed'August 9, 1924. Serial No. 731,152.

This invention-relates to a new and improved threading machine of therolled .cited, the entire elimination of knock out mechanism, and aflushing of the dies by I the lubricant which facilitates the threadrolling operation *and cleans the dies of chips, etc., as well as toprovide for an easy and convenient adjustment of-the parts to conform tothis movement of 'the'blank,

and for blanks of various sizes, and to make the machlne. entirelyautomatic In Its action.

- These and other desirable results are obtained by a machine of simpledesign, wherein threading dies of standard size may be readily installedand which can be operated at the highest efiicieii'cv with the minimumlabor and attention. 9

To these, and other ends, my inventio tions .of parts as; will behereinafter described and more particularly pointed out in the claims. I

In thepreferred form of the threading machine shown in the drawings; 10desig-' nates the pedestal or base, the lower portion of which'is notshown but may be of any desired constructlon, having an apron 11projecting from one face thereof, and

secured upon the top thereof in any con venient manner is the body.member 12,

which is arran ed so as to lie in an inclined plane substantlally asshown in Figure 1,

this an 1e being about 30. Journaled in' this b0 y memiiier is a shaft.13 having a driving Wheel 14 upon one end anda pinion 15 on the otherend,:the teeth of which mesh into those of a spur gear 16 mounted theteeth of which mesh into those of a gear 18 upon a shaft 19. Slidablymounted within the body member 12 is the gate 20 upon a shaft having apinion- 17 thereon, consists in the threading machine, having. certaindetails of construction and combina-- that is connectedwith the spurgear by the i pitman 21 whereby a reciprocatory move ment is" impartedto the gate. -A gib' 22- and a cap. 23, both of which are associatedwith the body 12 provide convenientmeans' holding the gate in operativerelation with the body meniber 12. Secured within the inner face of ;thegate 20 is the movable die 24:, heldtherein by'the clamps 25 or similarmeans. Adjustably secured upon the bodymember 12 by the screws 31 isthedie block 26, to which the stationary die 27 is secured by the clamp28. This die block is adjusted toward and away from the gate-by thescrew 29 threaded therein and the'stopscrews 30 which are threaded inthe body member 12, the inner ends of which im inge against the dieblock, as shown in igure 2..

As an additional support: for the die block .26 and to minimize thestrain upon the bolts and screws holding the same, a stud 32, or thelike, may be fixed in the body 12 against the lower edge of the dieblock, as shown particularly in Figure 2.

Both the movable die 24 and the stationary die 27 are provided with theusual grooves in the working faces thereof and by means of which thethread is rolled in the blank. x

The chute mechanism, arranged in the same angle as the body member 12,comprises in part the fixed side plate 33, an

adjustable side plate 34 and a cap or cover 35. The adjustable plate 34,is secured to a movable bracket 36 that is adjustably held upon the bodymember 12 by the screws 37, so as to be moved toward and away from thefixed side late 33. This section varies the width of t e open space 40between the chute plates'and accommodates blanks of various diameters.

Preferably, the cap or cover 35 is adjustabl secured to'the side chuteplate 34 at one en by the clip 38 and at the lower end to the bracket 36by the screws 37 having a thumb nut thereon. Movement of this cap towardand away from the top; of the plates 33 and 34 accommodates the heads orblanks of various sizes.

angle of inclination of the bodynnember 12 by means of the screw 44 andlocked in these several positions by the bolts 45 that pass throughslots 46 therein. This bracket 43 is mounted upon the pedestal or base10 and adjusted by means of the screw 47 in a path at a right angle tothe angle of inclination to the body member 12 and there locked in anyof its several positions by the bolts 48 in a well known manner. By thusmounting the hopper, it may be moved as a unit v to any desiredposition'without varying its angular relation to the body 12 or to thechute mechanism- The blanks are discharged-from the hopperin a wellknown manner by a'vertically -.movable plate 49 actuated by a pitman 50same, or discharging the blanks therefrom,-

connected therewith and to the gear 18. The hopper, the-method ofoperating the constitutes no part of this present invention.

Fixed to the body member 12 is a slide bracket 51 to the outer end ofwhich is'secured a spring arm 52 and within which is mounted a slide 5.3that is held therein by the gib 54. Motion is imparted to this slide 53awa from the gate 20 by a cam 55 secured to't e undersideof the ateand-movable therewith, and a cam ro 56 fixedto the inner end of theslide and held in contact with the cam by the spring 57 which en circlesa spring pin 58 in the spring arm 52 and lies within the bore 59 of theslide 53. As the gate moves to the left the parts are as shown in Figure2, at which time a blank is between the faces of the threading dies, theslide 53 is moving away from the gate against the tension of the spring57 which is thereby compressed. Upon the return stroke toward the gateby the expansion of the spring 57, the roll 56 thus maintaining itscont-act with the cam 55.

Adjustably secured to the slide 53 by the bolt 60 is the finger bracket61, carrying the pusher (plate 62 that is held in any of its positionsby the screw 63. A rock 7 ends engages a pin in the finger bracket 61and the other end a pin 71 in the rock lever 64 and by reason thereofexerts its tension so as to rock the lever 64 and hold the outer end ofthe finger 67 in its down position,

of the gate, the slide 53 is moved inwardly as shown in Figure 3, butwill yield and allow the same end of the finger to pass over the head ofa blank during theoutward movement of the slide. When the slide 53 nearsits outermost position the rock lever 64 engages a sto screw 72 in thepoppet 73 fixed in the side bracket 51 and. is rocked thereby and thefinger 67 moved to its up position. The blanks are delivered from the.hopper onto the chute mechanism and travel therethrough by gravity in awell known manner in an inclined path to the lower end of the chute. Thetimed relation between the reciprocating gate and the slide 53 is suchthat. the pusher plate 62 engages the lowermost blank in the in theblank is designated 90 and pushes the same in an angular path relativelythereto along the upper face of the die block 26 until it engages theface of the movable die 24 as shown in Figure 5. This action of thepusher finger in advancing the blank from the chute to the threadingdies is derived, from the spring 57 as above described so that if by,chance, the blank should catch -or for any other reason be impeded inits travel, the pusher plate will come to a stop instead of continuingto advance as if driven by positive means, tnus eliminating one veryserious cause of'difliculty in this type of mechanism. The upper face ofthe die blok 26 and the upper end of the fixed die 27 are arranged at asli ht downward angle transversel to that 0 that the blanks Wlll.continue'to travel downthe chute. so

wardly-during their transverse movement.

The blank, after its transfer to the dies is picked'up thereby androlled therebetween by the action of the movable die until it has passedthe end of the fixed die as shown by the broken lines in Figure 5, atwhich time it is released and drops by gravity onto the guide tray 7 4from which it drops into the .apron 11. Thus the blank, from the time upbetween the dies after being delivered thereto by the transfermechanism, but this engagement is assured by the means which comprises apusher 75 having ashank 76 thereon. that is supported in blocks' 77connected by screws 78 or the like, to the plate 79 separably secured tothe cap 23. The spring 80 surrounding this shank 76 between the blocks-77 exerts its tension so as to move the pusher toward the fixed die 27;

When the pusher plate 62 is ithdrawn the nose 81 of'the pusher 75projects into'the open space between the stationary and movable dies. Asthe blank is advanced toward thedies from the chute, it first engagesthe angular face 82 of the head 75 and presses the same inwardly againstthe tension of the spring '80 until the parts are in the positionsubstantially as shown by full lines in Figure 5, at which time the nose81 is in cont'actwith the s'hankof the blank and applying a slightpressure thereto suificient to insure its entrance between thedies.

Other types and forms of pusher mechanism may be substituted as may seemdesirable. The slide 53 and associated parts are held stationary in itsoutermost position for the purpose of adjustment of the parts etc. by aplunger 98 movable within the chamber 83 and pressed downwardly by thespring 84. A knurled thumb button 85 is fixed on the upper end of thisplunger and projecting therefrom at aright angle to its'length'is a pin86. In Figure 4 this. plunger is shown in its down position andprojecting into an opening '87 7 in the slide bracket 51 and the pin 86is in a notch 88 in the slide. When the parts are in the ,positionthusdescribed, the slide'is held in its outermost position againstmovement. By lifting the plunger upwardly against the tension ofthespring 84, and the pin 86 out of the notch 88 and then rotating thesame slightly so that the pin rests upon the top of the lug 89,substantially as shown in Figure 1, the plunger 98 is withdrawn into thechamber 83 and above the opening 87 and the slide 53 isoperable,asbefore, by the cam 55 and the spring 57. j-

As the diesmove in-an inclined plane, the

' and engagin lubricant applied thereto readil washes and cleans thedies, due to the fact that it travels through the'grooves therein. Inthe old type machines, w erein the dies travel in a sub.-

stantially horizontal plane, the stream of lubricant was unable to flushand clean the dies. Thus the chips frequently remained dies, etc., asshown herein, the lowermost blank in the column, if it has a countersunkhead or the like, engages the upper corner of the upper face of the dieblock 26 opposite the chute and is there suspended by the head at threepoints, two of which points are the lower inside upper corners of thechute plates 33 and 34, and the thirdpoint the upper .corner edge of thedieblock '26. Sometimes. with this form of blank, the shank. instead oflyin parallel with the slot or open space 40 in the chute and also withthe slot leading' therefrom alongside the;

upper face of the die block 26, has a tends ency to out, by reason ofthe weight of the blanks in the chute resting against it.

This results in the lower end thereof being inclined toward the threadindies. When soarranged, the shank of t e next blank inthe column ofblanks in the chute is scrowded by gravity, assisted b the weight of theother blanks in the co u-mn, into a position where it is under the shankof the owermost blank, which it? will be remembered, is inclined alittle toward the dies.

The pusher plate 62, now instead of engaging the shank of the lowermostblank, frequently contacts with the next succeeding blank andas theshanks of the two lowermost blanks are interlocked and thepusher plateis unable to perform its function, re-

mains stationary. The streamof blanks to the threading dies is then cutoff. This sitnation does not occur except with blanks havingacountersunk head and a relatively long shank. To prevent such possibleinterlocking of the two lowermost blanks and to insure a positive feedof a stream of blanks to the dies, Ihave, inserted a latch 91 in theblock. 92, having a roundedouter end and secured to the chute plate 33at .its lower. end. This latch is hinged upon a pin 93 below the top ofthe block\ (see Figure v7) the rear face thereof is a spring 94 whlehexerts its tension so as to i 55 to" positively withdraw thepusher-thatmove the inner end of the latch toward the die block 26, the positionshown in Figure 5. The limit of the outward position of the outer end ofthis latch is determined by the 5 contact of the heel thereof with thebottom of the recess on the block 92 in which it is mounted. When inthis out position, as-

shown in Figure 5,there is an open space between the outer end of thelatch and the If the shanks of the blanks are so short,

that the weight of the head outweighs that of the shank, the lowermostblank in the column of blanks in the chute has a tendency to occupy aposition substantially as shown in Figure 6, at which time the head ofthe.

next succeeding blank crowds under the head of the lowermost blank inthe column.

In this position the shank of the lowermost blank projects back into theslot 40 and by reason thereof is locked against movement by the pusherplate 62 and hence is not fed to the threading dies. To obviate thisdifficulty and insure a proper alignment of the lowermost blankrelatively to the chute slot and the pusher plate, the inner lowermostcorner of the chute plate 33 15 formed with an undercut notch 96 whereinthe wall 97 40 thereof is at an angle to both the inside faces of thechute plate 33 and the end thereof and terminates in a point at theintersection of the inner and lower edges of the top face of said chuteplate 33, substan- 'tially as shown in Figures 6 and 7 When thelowermost blank in the chute is in the position substantially as shownin Figure 6, it is engaged by the pusher plate 62 and its alignment isrectified by reason of the engagement of the end of the shank with theangular wall 97 and after passing the end of the chuteplate 33 isreadily advanced to the threading dies.

It is desirable with some classes of work ro jects the blank between thedies, instea of maintaining it under aforward pressure, aswith thepusher 5. To this end I have provided a mechanism, whichconsists of apusher slide 116 which is substituted for the pusher slide 75, the shank117 thereof being supported in the blocks 77 and projects rearwardlytherefrom with a collar 118 fixed thereon. Rotatable in the journalblock 107, conwas nected with the cap 23 is a shaft 106 havin on one endan arm 109, which at its lower en straddles the shank 117 and contactswith the inner face of the collar 11% substantially as shown in-Figure10. A rocking movement is im arted to this shaft 106 from a cam 102, sown herein as mounted upon the hub 101 of the pinion 17 and aga nstwhich rides a cam roll '103 carried b the lever 104 pivotally connectedto the rame by the stud 105. A rod 110 projecting through a swivel'block 111 on the lever 104 i at one end and a swivel block 112connected with the arm. 109 at the opposite end is secured in itsadjusted positions by the nuts 113. Thus means are provided forconnecting the-lever 104 with the arm 108, whereby the shaft 106 isoscillated in timed relation with the other parts. By this mechanism thepusher 116 is withdrawn against the tension of the spring so that theforward end thereof is in rear of the inclined face of the block 114,secured to the fixed plate 33 by the screw 115 until the blank is in"substantia'ly the position shown in Figure 11. An ad ustable stop screw119 provides means for limiting the movementof the pusher toward thestationary die 27. At

the instant the blank is brought up against the movable die 24 thepusher slide 116 moves forward and applies sufficient pressure to theblank to insure its engagement between the dies.

The pusher slide 116 is then withdrawn and retains a position with itsfront end in rear of the angular face of the guide block 114substantially as shown in Figure 11, until the next blank is presentedin front thereof.
